AbstractThis paper examines the control system characteristics of a vessel that uses Z-drives to actively reduce roll motion. Active roll control systems that use rudders and fins have been in existence for many years and the capabilities of such systems have been studied extensively. As an actuator, the Z-drive suffers from many of the same limitations as rudders; for example, the vessel?s steering is also closely linked to the rudder motion. The Z-drive has an advantage over rudders and many fin-based systems in that it has the potential to be an effective actuator for roll motion reduction at low and even zero forward speeds: conditions in which a rudder is completely ineffective. Full-scale trial data is used to establish some design principles for a roll reduction system based on Z-drive operation.
